Troubleshooting S7 Edge that doesn’t power on after the Nougat update

Problem: There was an update for my S7 Edge and I followed the instructions on how to download and install it and I think everything went well. I left the phone while it was still downloading knowing that it would continue the update process like it did before. When I got back, the device was already showing the S7 Edge logo so I thought it was just booting up. It remained on that screen for several minutes before I decided to just restart it. It did turn off but could no longer power up. When I press the power key, it doesn’t respond. What can I do to power on my phone? Thank you.

Troubleshooting: There are some things we need to look into so that we can tell what exactly happened to your phone and what needs to be done to bring it back to life. But before anything else, I want you to know that this kind of problem isn’t new. A lot of Galaxy device owners already encountered it and majority of them were able to fix the problem, in our case however, we cannot guarantee that the problem can be fixed but you still need to troubleshoot as you may be saving yourself from a lot of trouble. Here’s what needs to be done…

  1. Force reboot your phone. It’s possible that your device crashed, which naturally leaves the firmware and the hardware frozen and unresponsive no matter what you do. We don’t know for sure if it’s really the case but this must be the first assumption we have to make when troubleshooting as it is very effective is dealing with similar issues. Just press and hold the Volume Down and the Power keys together for 15 seconds and your device may reboot normally provided there’s enough battery left to power it up.
  2. Charge your phone and do force restart it. Assuming the device didn’t respond when you first did the forced reboot procedure, we have to assume there’s not enough battery left so plug the charger in and then do the same procedure while the charger is connected. But aside from this purpose, it will also tell you immediately if it’s a more serious hardware issue. Usually, the phone will display the usual charging icon or light up it’s LED indicator. So, if none of these things display even after doing the forced reboot procedure, proceed to the next step.
  3. Attempt to boot your phone up in Safe Mode. You have to do this to rule out the possibility that the problem is caused by one of your third-party apps. If the phone boots up in safe mode successfully, then we certainly say that the problem is caused at this point in our troubleshooting and the next thing you need to do is find the apps that are causing the problem, clear their cache and data or uninstall them if a simple app reset won’t work. You may have to uninstall more than one app to get rid of the application that’s causing the problem. The steps on how to boot your phone up in safe mode can be found below.
  4. Attempt to start your phone up in Recovery Mode and wipe cache partition. We are not actually trying to fix this problem by wiping the cache partition, we’re just trying to see if it can still boot up in recovery mode and if successful, try to wipe the cache partition as the issue may have been caused by some corrupt caches. Refer to the steps below on how to wipe cache partition of your Galaxy S7 Edge.
  5. Try to Master Reset your phone if it boots up in Recovery Mode successfully. You do this only if the phone can successfully bring itself to boot in recovery mode and if wiping the cache partition didn’t work. This procedure, however, will delete all your files and data and you don’t have a chance to back them up but you really don’t have much of a choice. The steps on how to wipe the cache partition and master reset can be found below.
  6. Send the phone in for checkup and repair. If the phone failed to boot up in recovery mode or if both the wiping of the cache partition and master reset failed, then you have no other option but to send the phone in for repair and let the tech handle it for you.
